The invention provides a trigger key device, which aims to provide better tactile feedback experience for a user, so that the sensory requirements of the user on related equipment (such as various operating handles, toy guns, virtual reality equipment, augmented reality equipment and the like) are met.
The following will explain the specific structure of the trigger button device proposed by the present invention in a specific embodiment, and take the vertical placement of the trigger button device as an example for description:
as shown in fig. 1, fig. 2 and fig. 5, in an embodiment of the trigger button device 100 of the present invention, the trigger button device 100 includes:
a base 10;
a key 20, wherein the key 20 has a user operation end 21 and an inner movable end 22 connected with each other, and a portion of the key 20 located between the user operation end 21 and the inner movable end 22 is rotatably connected to the base 10, so that the user operation end 21 can move closer to or away from the base 10;
the moving piece 30 is arranged on one side, away from the base 10, of the inner movable end 22; and
the driving assembly 40 is arranged on the base 10 and is in transmission connection with the moving member 30, so that the moving member 30 can approach or depart from the base 10;
when the moving member 30 approaches the base 10, the moving member 30 presses the inner movable end 22 to move the user operating end 21 away from the base 10.
It is understood that the base 10 can provide a stable and reliable mounting platform for the keys 20, the moving member 30, the driving assembly 40, and the like. The base 10 may be a separate component from the housing of the electronic device, which is specially provided for mounting the keys 20, the moving member 30, the driving assembly 40, and the like, or may be a housing of the electronic device.
The keys 20 may be keys 20 of various operation handles (such as a game handle), a trigger of a toy gun, keys 20 of a virtual reality device (VR device for short), or keys 20 of an augmented reality device (AR device for short).
The key 20 has two ends, a user operation end 21 and an inner movable end 22, and the portion between the two ends of the key 20 is assembled with the base 10 in a rotating connection manner, so that the user operation end 21 can move close to or away from the base 10, and the inner movable end 22 can move away from or close to the base 10; the specific process is as follows: the approach of the user operation end 21 to the base 10 is accompanied by the approach of the inner movable end 22 to the base 10; the process of moving the user operating end 21 away from the base 10 is accompanied by the process of moving the inner movable end 22 closer to the base 10.
Wherein the user operation end 21 is used for contacting with the finger of the user, and can be "sunk" or "bounced" relative to the base 10, so as to apply force to the finger of the user or cancel the force applied to the finger of the user, thereby completing the interaction with the user. The inner active end 22 is then used to cooperate with the displacement member 30 and the drive assembly 40, specifically:
when force feedback is desired to be given to the user, the drive assembly 40 applies a force toward the base 10 to the inner movable end 22 by controlling the movement of the moving member 30 toward the base 10 (i.e., "sinking" relative to the base 10), thereby moving the inner movable end 22 toward the base 10 (i.e., "sinking" relative to the base 10); at this time, the user operating end 21 moves away from the base 10 (i.e., "bounces" relative to the base 10), and applies a force to the user's finger, giving a force feedback effect to the user.
When force feedback is not required to be given to the user, the driving assembly 40 gives the inner movable end 22 sufficient activity space by controlling the moving member 30 to move away from the base 10 (i.e., "bounce" relative to the base 10), so as to avoid affecting the user to continuously press the user operating end 21; at this time, the force applied to the user's finger is canceled, and the force feedback given to the user is canceled.
Therefore, a better tactile feedback experience is provided for the user, and the sensory requirements of the user on related equipment (such as various operating handles, toy guns, virtual reality equipment, augmented reality equipment and the like) are met.
As shown in fig. 1, 2 and 5, in an embodiment of the trigger button device 100 of the present invention, the base 10 has a mounting surface 111, and a portion of the button 20 located between the user operating end 21 and the inner movable end 22 is rotatably connected to the mounting surface 111;
the driving assembly 40 comprises a screw rod 41 and a nut 42, the screw rod 41 is convexly arranged on the mounting surface 111 and can rotate relative to the mounting surface 111, and the nut 42 is sleeved on the screw rod 41 so as to be close to or far away from the base 10 in the rotating process of the screw rod 41;
the moving member 30 is fixed to the nut 42 to move with the nut 42.
It can be understood that, the screw rod 41 and the nut 42 are used as the main transmission mechanism, which not only can stably and reliably control the process that the moving part 30 approaches the base 10 and the process that the moving part leaves the base 10, but also can realize the force feedback function of the key 20; but also has the advantages of faster force feedback response speed, more linear output, lower noise and the like.
It should be noted that the moving member 30 and the nut 42 may be two separately manufactured components, and then connected together by means of, for example, adhesive bonding, welding, screwing, or the like, or may be an integrally formed integral structure.
As shown in fig. 1, 2 and 5, in an embodiment of the trigger key device 100 of the present invention, the driving assembly 40 further includes a spring 45, the spring 45 is sleeved on the screw rod 41, one end of the spring 45 abuts against the mounting surface 111, and the other end abuts against the nut 42.
It can be understood that the nut 42 can be tightly pressed on the screw rod 41 by the spring 45, so that the idle stroke between the nut 42 and the screw rod 41 is avoided, and the force feedback effect is improved.
As shown in fig. 1 to 3, in an embodiment of the trigger key device 100 of the present invention, the mounting surface 111 is convexly disposed on the first auxiliary structure 13, a sliding groove is disposed on a surface of the first auxiliary structure 13 facing the nut 42, the sliding groove extends along a length direction of the lead screw 41, the nut 42 has a sliding portion 421 disposed facing the sliding groove, and the sliding portion 421 is inserted into the sliding groove.
It can be understood that, by using the sliding groove, the movement of the sliding part 421 can be standardized to be a linear movement along the length direction of the screw rod 41, so as to prevent the sliding part 421 from rotating around the axis of the screw rod 41, prevent the screw 42 from rotating, and further make the linear movement process of the moving part 30 along the length direction of the screw rod 41 more stable and reliable.
In the present embodiment, the first auxiliary structure 13 is a plate-shaped structure with a certain curvature, and the plate-shaped structure with a certain curvature is arranged around the outer side of the screw rod 41 along the circumferential direction of the screw rod 41. Thus, the first auxiliary structure 13 can also protect the screw rod 41, the nut 42, the moving member 30 and the like positioned on the inner side of the first auxiliary structure to a certain extent, reduce the possibility that the screw rod 41 and the nut 42 are disturbed by the outside, and improve the stability and the reliability of the matching of the screw rod 41 and the nut 42.
As shown in fig. 1, 2 and 5, in an embodiment of the trigger key device 100 of the present invention, a second auxiliary structure 14 is protruded from one end of the first auxiliary structure 13 away from the mounting surface 111 toward one side of the screw rod 41, and one end of the screw rod 41 protruding from the mounting surface 111 is rotatably inserted into the second auxiliary structure 14.
It can be understood that, with the second auxiliary structure 14, the position of one end of the convex mounting surface 111 of the screw 41 can be regulated, which avoids the end from generating poor effects such as deviation and swing, and improves the stability and reliability of the screw 42 fit of the screw 41.
In this embodiment, the second auxiliary structure 14 is a plate-shaped structure, which is disposed opposite to the mounting surface 111, and the nut 42 moves linearly between the plate-shaped structure and the mounting surface 111. In this way, the second auxiliary structure 14 can also protect the screw rod 41, the nut 42, the moving member 30 and the like located inside the second auxiliary structure to a certain extent, so that the possibility that the screw rod 41 and the nut 42 are disturbed by the outside is reduced, and the stability and the reliability of matching the screw rod 41 and the nut 42 are improved.
As shown in fig. 1, fig. 2 and fig. 5, in an embodiment of the trigger key device 100 of the present invention, two mounting brackets 15 are convexly disposed on the mounting surface 111, the two mounting brackets 15 are disposed opposite to each other, each mounting bracket 15 is provided with a shaft hole, the two shaft holes are disposed opposite to each other, the key 20 is disposed between the two mounting brackets 15, two sides of the key 20 are respectively provided with a rotating shaft 23, and each rotating shaft 23 rotatably penetrates through one shaft hole.
It can be understood that, with the two mounting brackets 15, not only the rotary connection of the key 20 with the base 10 can be realized; the position of the key 20 is raised, which is more convenient for the movement of the user operation end 21 and the inner movable end 22, and avoids the interference with the installation surface 111; meanwhile, the 'clamping' of the key 20 can be formed, so that the two sides of the key 20 are more balanced, and the rotation process of the key 20 is more stable and reliable.
In this embodiment, the mounting bracket 15 is a plate-like structure, and the two plate-like structures are disposed opposite to each other to form a clamping space for "clamping" the button 20. Therefore, the surface of the plate-shaped structure facing the clamping space is smooth, and the plate-shaped structure can also play a role in guiding the rotation process of the key 20, so that the stability and the reliability of the rotation of the key 20 are further improved.
As shown in fig. 1, fig. 2 and fig. 5, in an embodiment of the trigger key device 100 of the present invention, a stop block 16 is protruded from an inner side surface of the mounting bracket 15 for stopping the key 20 when the inner movable end 22 is away from the base 10.
For convenience of description, it is defined that the maximum position of the user operation end 21 "sinking" is a sinking position, and the maximum position of the user operation end 21 "bouncing" is a bouncing position, so that when the user operation end 21 sinks from the bouncing position to the sinking position, the inner movable end 22 moves from the position closest to the base 10 to the position farthest from the base 10; at this time, the stopper 16 is used for preventing the user operating end 21 from sinking further, and is used for preventing the inner movable end 22 from further moving away from the base 10; that is, the stopper 16 blocks the moving direction of the inner movable end 22 away from the base 10, so as to prevent the inner movable end 22 from excessively leaving the base 10 to cause the structure to fail, damage, and the like, thereby ensuring the stability and reliability of the trigger key device 100.
As shown in fig. 1, fig. 2 and fig. 5, in an embodiment of the trigger key device 100 of the present invention, the trigger key device 100 further includes a torsion spring 60, the torsion spring 60 is sleeved on the rotating shaft 23, and two supporting arms of the torsion spring 60 are respectively fixed to the mounting bracket 15 and the key 20, so as to drive the user operating end 21 to reset after being pressed.
It can be understood that, with the torsion spring 60, not only the automatic reset of the key 20 can be realized, but also the structure is simple, the manufacture is convenient, the installation is fast, and the stability and the reliability are excellent.
As shown in fig. 2 and 4, in an embodiment of the trigger button device 100 of the present invention, the driving assembly 40 further includes a motor 43 and a speed reducing mechanism 44, and the speed reducing mechanism 44 is in transmission connection with the screw rod 41 and the motor 43, respectively.
It can be understood that, by using the speed reducing mechanism 44, the high rotational speed output of the motor 43 can be reduced to be suitable for the low rotational speed output of the lead screw 41, so that the moving speed of the screw 42 and the moving member 30 connected with the screw 42 meets the force feedback output requirement, and a better tactile feedback experience is provided for the user.
As shown in fig. 2 and 4, in an embodiment of the trigger key device 100 of the present invention, a mounting cavity is formed in the base 10, the motor 43 is disposed in the base 10, an output shaft of the motor 43 is inserted into the mounting cavity, and the speed reduction mechanism 44 is mounted in the mounting cavity.
It can be understood that, by using the installation cavity of the base 10, not only can the speed reducing mechanism 44 be protected, the possibility of external disturbance on the speed reducing mechanism 44 is reduced, and the stability and reliability of the operation of the speed reducing mechanism 44 are improved; but also improves the integrity of the trigger key device 100 and facilitates the placement and installation of the trigger key device 100.
In this embodiment, the base 10 is mainly formed by covering the upper case 11 and the lower case 12. The upper shell 11 includes a top plate and a surrounding plate surrounding the top plate (wherein, one side surface of the top plate forms the mounting surface 111, the surrounding plate is protruded from the other side surface of the top plate and is located at the outer periphery of the top plate), and the lower shell 12 is in a plate-shaped structure and covers the bottom of the upper shell 11 to form a mounting cavity with the top plate and the surrounding plate. It can be understood that the arrangement of covering the upper shell 11 and the lower shell 12 can facilitate the assembly and disassembly of the base 10, thereby facilitating the assembly of the speed reducing mechanism 44, the motor 43, the screw rod 41 and the like. In addition, it can be understood that the base 10 may further include the first auxiliary structure 13, the second auxiliary structure 14, the mounting bracket 15, the stopper 16, the spring 45, the torsion spring 60, and the like, which are disposed on the mounting surface 111 as described above.
As shown in fig. 2 and 4, in an embodiment of the trigger button device 100 of the present invention, the speed reduction mechanism 44 includes a primary speed reduction gear set 441 and a secondary speed reduction gear set 442, an input end of the primary speed reduction gear set 441 is connected to an output shaft of the motor 43, an output end of the primary speed reduction gear set 441 is connected to an input end of the secondary speed reduction gear set 442, and an output end of the secondary speed reduction gear set 442 is connected to the lead screw 41.
In the present embodiment, the primary reduction gear set 441 includes a first gear 4411 and a second gear 4412, and the pitch circle diameter of the first gear 4411 is smaller than the pitch circle diameter of the second gear 4412; the secondary reduction gear set 442 includes a third gear 4421 and a fourth gear 4422, the third gear 4421 having a pitch circle diameter smaller than that of the fourth gear 4422; also, the pitch circle diameter of the third gear 4421 is smaller than the pitch circle diameter of the second gear 4412. Specifically, the first gear 4411 is sleeved on the output shaft of the motor 43 to rotate along with the output shaft of the motor 43; the second gear 4412 is engaged with the first gear 4411 to rotate with the first gear 4411; the third gear 4421 is disposed coaxially with the second gear 4412 to rotate with the second gear 4412; the fourth gear 4422 is engaged with the third gear 4421 to rotate with the third gear 4421; and, the fourth gear 4422 is also in transmission connection with the lead screw 41 to drive the lead screw 41 to rotate.
As can be appreciated, with the two-stage deceleration, not only the movement rate of the screw 42 and the moving member 30 connected to the screw 42 can be made to meet the force feedback output requirement, thereby providing a better tactile feedback experience for the user; and simple structure, convenient manufacture, swift installation, stability and reliability are also comparatively excellent simultaneously.
In addition, it should be noted that the mounting cavity has a top wall and a bottom wall which are oppositely arranged, a first rotating shaft 443 can be supported between the top wall and the bottom wall, two ends of the first rotating shaft 443 are respectively rotatably connected with the top wall and the bottom wall, and the second gear 4412 and the third gear 4421 are both sleeved on the first rotating shaft 443.
